Rowling's first part documents the historical background to the fictional sport, its rules and examples of controversial moments, such as the 1877 match at Kazakhstan's Ryn Desert, known as the Tournament that Nobody Remembers.

The second installment will be posted on March 21, and will include "amusing recaps of some notable recent matches that have been held every four years since 1990".

Quidditch's history also seems to be inspired by recent struggles involving the Sochi Olympics and the upcoming FIFA World Cup in Brazil.

"The ICWQC [International Confederations of Wizards Quidditch Committee] has the unlucky job of regulating this contentious and anarchic competition," Rowling writes.

"A source of vehement disagreements, a security risk for all who attend it and a frequent focus for unrest and protest, the Quidditch World Cup is simultaneously the most exhilarating sporting event on earth and a logistical nightmare for the host nation."

In another section, she adds: "The rulebook concerning both on- and off-pitch magic is alleged to stretch to 19 volumes and to include such rules as 'no dragon is to be introduced into the stadium for any purpose including, but not limited to, team mascot, coach or cup warmer' and 'modification of any part of the referee's body, whether or not he or she has requested such modifications, will lead to a lifetime ban from the tournament and possibly imprisonment'."

Pottermore CEO Susan L Jurevics said: "We're committed to being the only digital destination where fans can discover new original content about the world of Harry Potter from JK Rowling.

"History of the Quidditch World Cup helps us not only fulfil that mission, but it also serves to entertain and delight our community."
